Portlet, JSF, Spring

[Wayne Glanfield <wa...@hotmail.com>]

I'm currently in the process of porting a JSF(MyFaces1.0.9), Spring-1.2.5, 
Hibernate-2.1 application to Jetspeed2m3 portal. I'm relatively new to all 
of these frameworks so appologies for any dumb questions.

I have managed to get as far as configuring and displaying my application as 
a portlet, however, I have run into problems when retrieving the external 
context (normally the ServletContext) when the spring service layer is 
called from JSF page.

My initial application retrieved the external context using something like 
this (appologies, for lack of actual code - we are not permitted to have 
internet access for various reasons at work)

ServletContext context = (ServletContext) 
FacesContext.getCurrentInstance().getExternalContext().getContext();

This returned a servletContext which is then passed to a static spring 
utility class to retrieve the spring ApplicationContext. The spring 
ApplicationContext is then used to return a reference to the service layer 
and DAO.

this.appContext = 
WebApplicationContextUtils.getRequiredWebApplicationContext(context);
this.catalogService = 
(CatalogService)this.lookupService(CATALOG_SERVICE_BEAN_NAME);

Now when the JSF page is running in a portlet the returned external context 
is JetseedPortletContext.

My question is, how do i obtain a reference to the ServletContext or should 
I be using the JetspeedPortletContext

Any help greatly appreciated.

Wayne,

Spring Portlet MVC has a corresponding PortletApplicationContextUtils 
that you can use in the same manner.  Specifically:

    this.appContext = 
PortletApplicationContextUtils.getRequiredWebApplicationContext(context);

Where 'context' is your PortletContext should work just fine.

See the following for more info on Spring Portlet MVC:

    http://opensource.atlassian.com/confluence/spring/display/JSR168/Home

It will be part of Spring 1.3, but you can use the downloads at this 
site to solve your problem now.
